IncidentThe Chiles-Whitted Encounter (24 July 1948)

Captain Clarence Chiles and First Officer John Whitted, flying an Eastern Air Lines DC-3 at ~5,000 ft southwest of Montgomery, saw a light close fast and described a wingless torpedo/cigar-shaped object ~100 ft long, ‘like a B-29 fuselage,’ with two rows of brightly glowing rectangular windows and a long orange-red exhaust, passing on their right then pulling up into the clouds with a burst of flame over ~10-15 seconds; a passenger glimpsed only a streak of light. Project Sign built a trajectory map and noted an apparent corroborating ground sighting near Robins AFB; Edward Ruppelt later wrote the case ‘shook them worse than the Mantell Incident.’ Chiles-Whitted is widely cited as one of the cases that pushed Sign to draft its Top Secret ‘Estimate of the Situation’ concluding the objects were interplanetary - rejected by Air Force Chief of Staff Hoyt Vandenberg (~October 1948) as evidentially insufficient and, per Ruppelt, destroyed, after which Sign was reoriented as Project Grudge. By 1959 Blue Book attributed the sighting to a bright fireball/meteor (the Delta Aquariids; an Alabama observer counted ~15 meteors that hour), with the structured ‘craft and windows’ read as a perceptual ‘airship effect.’ Even Hynek, who proposed the meteor, wrestled with the windows detail. A foundational, policy-driving case.
